machines and more particularly to changemaking machines.

Among other objects the invention is in tended to provide a machine ofSimple construction which shall be capable of making any desired changecombination for coins of any practicable denomination and which ispreferably inclosed against tampering and operable by simple externalmeans.

The character of the invention may be best understood by reference tothe accompany. ing drawing, in which:

Fig. 25 is a detached perspective ofillustrative change-throwing keys. Figs. 26 and 27 are detail sideelevations of the change-throwing mechanism shown diagrammatically inFigs. 19 to 24 inclusive. Figs. 28 to 31 inclusive are detached detailviews of an illustrative form of registering mechanism hereinafter morefully described. Fig, 32 is a detached detail end elevation of anauxiliary coin-throwing mechanism by which the coin raceways may beemptied into a preferably inclosed drawer of the machine.

. The specific machine shown in the drawings is well adapted for use onpay-as-youenter railway cars, and for convenience, will be describedas-applied to'such use, although it is to be understood that theinvention is The specific machine shownin the drawings is constructed toreceive a nickel, a

dime, a quarter or a fifty-cent piece, which, when deposited, ismaintained temporarily in position to be inspected by the operator. If,upon inspection, the operator desires to reject the coin, he may throwit out of the machine by depressing the rejecting key. If the coinpasses'inspection, it is admitted into the-machine by the operatordepressing an admission key corresponding to the denomination of theadmitted coin. The coin so admitted may pass into a storage raceway fromwhich coins are taken in making change, or may be conveyed to a draweror other receptacle inclosed within the casing. I Depression of anappropriate admission key prepares the change-throwing mechanismresponding to the amount of change desired to be released and therebysuch amount of" change is released or ejected into an appropriate pocketaccessible to the depositor of the original coin. Various safe-guardingappliances are provided in the machine to prevent tampering anddishonest change making; these appliances comprise means for preventingmorethan single changethrowing operation for each deposited coin of alarge enough denomination to require change, and comprises also meansfor preventing any operation of the machine except upon deposit of oneof the particular coins to which the machine is adapted.

It is to be understood, of course, that the description in the nextpreceding paragraph is merely explanatory 'of the specific illustrativemachine of the drawings, and is not to be construed as limiting theinvention to the particular mechanism or organization therein specified.On the contrary, said illustrative machine is only exemplary of a greatvariety of organizations in which the invention may be embodied, and ofmodes of operation by which the invention may be practised.

Referring now to Figs. 1 to 5 inclusive, the machine comprises acoin-receiving hopper 30, having a slot 31 therein of such dimensions asto receive a fifty cent piece, or any smaller coin. When the machine isat rest the slot 31 is provided with a floor 32 upon which the depositedcoin rests. As shown in Fig. 2, the hopper 30 is'mounted upon trunnions34-34, permitting the hopper to be swung transversely toward theposition shown in Fig. 6, in which the slot 31 is swung out of itsnormal position over the floor 32, so that a coin with-in the hopper isdropped out and into a rejected-coin pocket 35. The walls of the hopper30, which are seen in front elevation in Fig. 2, are preferablytransparent to permit the operator of the machine to inspect each coinas it is inserted. If itproves to be an improper coin, or if for anyreason it is desired to be rejected, the hopper 30 is swung from theposition shown in Fig. 3, to that shown in Fig. 6, toreject the coin,which, in the specific instance described, drops by gravity into thepocket 35. The coin-rejecting mechanism just described may be actuatedby any practicable means. key 37 (Figs. 2 and 3) for this purpose may bearranged conveniently accessible to the operator and preferably adjacentother keys presently to be described. This key may constitute one end ofa lever 38, fulcrumed to the frame of the machine at 39, and connectedat its inner end 'to a coin-rejecting slide 40, having at its upper enda cam 41, arranged, when the slide 40 is elevated by depressing the key37, to strike a pin 42 on the hopper 30, thereby to rock said hopper onits trunnions 34 from the position shown in Fig. 3 to that shown in Fig.6. Fig. 2 shows within the hopper 30, in dotted lines, the various sizesof coins which the specific machine is adapted to handle, any or all ofwhich may be rejected in the manner and by the, means described above.

When a coin inserted in the hopper 30 is For example, a-

inspected and found satisfactory, it may next described. Assume thedeposit of a fifty cent piece in the position indicated by dotted linesin Fig. 2. To admit the same to the machine the operator depresses a key45 (Figs. 2 and 7) at one end of a lever 46, similar to the lever 38shown in Fig. 2, the inner end of said lever 46 being connected to afifty-cent-admission slide 47 shown in Figs. 2, 3, 4 and 5. Normally,when at rest the slide 47 stands in the position shown in Fig. 3, itsupper end being mounted to slide in a frame member 49, extending acrossthe machine. When in this position the latching end'50 of aslide-locking lever 51 rests, as shown in Fig. 3, upon the side of theslide 47 the upper end of said lever 51 constitut ing a detector 52which, at the appropriate time, feels for a coin in the slot 31 of thehopper. When the slide 47 is elevated by depressing the key 45 a recess54 is presented opposite the latching end 50 of the lever 51,

permitting the detector 52 to be pressed toward the right in Figs. 3, 4and 5, to feel for coin in the slot 31. If the detector 52 encounters acoin in the slot 31, the latching end 50 is held out of the recess 54,leaving the slide 47 free to be elevated to'admit the .coin as presentlydescribed; if, on the other hand, the detector 52 encounters no fiftycent piece in the slot 31, the entire lever .51. is permitted to takethe position shown in Fig. 4, wherein the latching end 50 has enteredthe recess 54 and engaged the tooth therein,

of the proper size, the slide locking lever 51 is thereby prevented fromrocking far.

enough to engage its latching end 50 with the locking tooth 54 of theslide 47, and the latter is thereby permitted to continue its upwardmovement. During such upward movement the detector 52 may rest againstthe coin in the slot 31, until a cam 57 on the slide 47 strikes thelatching end 50 and thereby rocks the lever 51 slightly contra-clockwiseto remove the detector 52 from contact with the coin so that thedetector shall not impede the admission of the coin when it has beenonce detected. By its. full upward movement the slide 54 operates ashutter 60, a part of which consists of the coin-supporting floor 32already referred to as standing normally underneath the slot 31. Theshutter 60 is carried upon a slide 61, mounted in the frame piece 49;connected to said slide is a lever 62, fulcrumed on the shaft 63 of thelever 51. A slot 64 in one end of the lever 62 receives a pin 65,projecting from a lug fixed to the slide 47. When the slide 47 is in itslowermost position the pin 65 stands at thelower end of the slot 64, asshown in Fig. 3. As the slide 47 moves upwardly the pin 65 travels inthe slot 64 at first without effect, until the slide reaches theposition shown in Fig.4, in which, if no coin be present in the slot 31,the latch 50 engages the recess 54 and locks the slide 47 againstfurther elevation. In such case, the pin 65 has no effect upon the lever62. If, however, the latch 50 is prevented from engaging the recess 54,by the presence of a coin in the slot 31, the slide 47 continues itsupward movement and the pin 65, reaching the upper extremity of the slot64, rocks the lever, throws the slide 61 toward the right and therebythrows the shutter toward the right to move the coin-supporting floor 32from under the slot 31 and to present thereunder a slot 67 in theshutter, which permits the coin to drop out of the hopper, through theslot 67 into a coin chute 68, through which the coin drops into acompartment of a drawer 69. at the be; a of the machine.

The coin-admitting mechanism just described is preferably incapable ofadmitting any coin except of a particulardenominationfor instance, afifty cent piece in the exemplary case described. As shown in Fig. 2, apin 70 will detain a fifty cent piece at the right hand end of thehopper in position to. be encountered by the detector 52. Any smallercoin than a fifty cent piece will roll beneath the pin 70, down theinclined temporary floor of the hopper to a position remote fromthe'detector 52, so that any attempt to depress the fifty cent key 45upon deposit of a quarter, or small coin, would be prevented by thedescribed action of the detector 52 and locking lever 51 arresting theupward movement ofthe slide 47. I

In the illustrative machine, when a quarter is introduced to the hopper30, it rolls down the inclined floor of the hopper under the pin 70 andstriking against a detent is detained in the position indicated indotted lines in Fig. 2. When so positioned'the quarter may be rejectedby depressing the key 37 as already described. To admit the quarter tostorage space Within the machine, an admission mechanism may be operatedb depressing a key 82 (Fig. 2) and thereby elevating a quarter-admissionslide 84. The

latter has a recess like the recess 54 shown ,upward movement, it movesa slide 88 to present a slot therein beneath the quarter and permit thelatter to drop into a storage raceway 90 inclosed within the casing ofthe machine. The construction and operation of the slide 84, lookinglever 86, and slide 88 may be substantially identical with that of thecorresponding parts shown in Fig. 3.

Nickels and dimes when deposited in the hopper 30 roll down the floorthereof until they strike the detent 80 which holds them insubstantially the position of the quarter in Fig. 2 until thenickel-admission key 96 or the dime-admission key 98 is depressed tolift the detent 80 aS next described.

As best shown in Figs. 8, 9, and 10, the detent 80 is mounted in avertical slide-way 100, and its shank 102 eXtends downwardly intoposition to be engaged and lifted, either by a. finger 104' projectingupwardly from a nickel-admission slide 107 or by a finger 110 projectingupwardly from an arm 111 on a dime-admission slide 114. Thus bydepressing either the dime-admission key 98 and elevating its slide 114,or the nickel-admis- SiOIl y 96 and elevating its slide 107, the detent80 is thereby lifted' topermit a coin to roll under the detent into anassorter next described. Up'to the point just reached in thisdescription, the dimes and nickels may have the same path in themachine; subsequently, however, it is desired to separate dimes fromnickels and to send all of each denomination to an appropriate storageraceway from which they may be thrown in making change.

Referring to Figs. 7 to 11 inclusive-a gate 116 is shown just in frontof the detent 80 and against which a coin strikes when the detent islifted. The gate 116 is fixed on a shaft 117 journaled in the top andbottom walls of a chamber 118 to which coins are admitted by lifting thedetent 80; In one position of the gate 116 shown in Figs. 10 and 12, anickel (indicated by N in Fig. 12) is guided into a nickel raceway 120:while in its opposite position the gate 116 closes the raceway 120 andguides a dime (indicated by D in Fig. 11) into a dime raceway 122.

To manipulate the gate for alternatively opening and closing therespective raceways. i

the shaft 117 has its lower end bent to form an operating arm 124 bywhich the shaft and gate may be oscillated. The gate operating arm 124stands between the dime-ad mission finger 110 and the nickel-admissionslide finger 104- as shown in Fig. 8; and each finger has a cam to throwthe arm 124 horizontally as the finger and its slide are elevated. Asshown in Figs. 9 and 10, the arm and gatev 116 are in position to admita nickel to its raceway 120; if now the dimeadmission slide 114 beelevated (by depressing the dime-admission key 98) the cam ori thefinger 110 will throw the arm 124 toward the right in Fig. 9 andcontra-clockwise in Fig. to close the nickel raceway and admit a dime tothe dime-raceway. This leaves the arm 124 in the dotted line position ofFig. 9 where it stands in the.

path of the cam on the nickel-admissionslide finger 104, which whenelevated opens the nickel raceway and closes the dime raceway. Thus thedepression of either the nickel or dime key and consequent elevation ofits slide, lifts the detent and lets the coin pass toward the gate,while at the same time the gate is thrown to proper position for guidingthe coin to its appropriate raceway. A dime so admitted does not pass atonce to its raceway but is detained in a chamber to travel of thedime-admissionslide 114 which.

is subject to the action of a slide-locking lever 132 having a detector134, which may be similar to the slide-locking levers and detectorshereinbefore described. In admitting a dime, the dime-admission key 98is first partially depressed to elevate its slide 114 far enough to liftthe detent 80 and permit thedime to take position over the slide 130;thereupon the dime stands in position to be detected by the detector134; and the dime-admission slide is permitted its full upward movementpast the'slidelocking lever 132, to push the slide 130 toward the rightin Fig. 10 to admit the dime finally to its storage raceway 122. Inadmitting a nickel, the nickel-admission key 96 is depressed to elevatethe nickel admission slide 107 and lift the detent 80, whereupon thenickel is admitted at onceto its raceway 120.

The above described slide-locking and detecting mechanisms are intended,as hereafter explained, to prevent operation of change-throwingmechanism except upon proper admission of a coin from which change is tobe made. .In the case of a nickel, however, no change is to be madetherefrom in the specific mechanism, and no change-throwing mechanismcanbe actuated upon admission of a nickel; therefore it is unnecessaryfor the purposes of the specific machine to'have any detecting operationinrespect to a nickel. I

It, is preferred that each coin admission or rejecting operation berecorded or other-' wise registered upon suitable registering mechanismprovided for that purpose. For instance, referring to Fig. 2, fourregisters 150, 151, 152 and 153 are shown. These registers may be of thewell-known Veeder type operated step-by-step by an oscillating arm.Referring to F ig'. 3, the register-150 is shown cooperating with thecoin-rejecting slide 40, the actuating arm 155 of the register150'overlying a pin 156 on the slide 40. 'Similar arms for the otherregisters cooperate with similar pins on the half-dollar admission slide47, the quarter admission slide 84 and thedime admission slide 114. 1

Referring now to Fig. 13, the quarter-storage raceway 90, thenickel-storage raceway 120 and the dime-storage raceway 122 areshown attheir coin-releasing ends adjacent the change-throwing mechanism. Asshown in Fig. 1, these several storage-raceways extend from their upperends down to their coin-releasing ends by a series of inclined chutesalong which the respective coins readily travel by gravity. In Fig. 13thedifferent denominations of coins are indicated by dotted lines in thepositions which they have in their raceways. When so positioned, eachcoin rests on a movable floor 160 (Fig. 18) of the change-throwingshutter. Under the dime raceways are two separately operablechange-throwing shutters arranged so that either one or two dimes may bethrown in a change-throwing operation. A similar shutter permits thethrowing of a nickel and another shutter permits the throwing of aquarter. The manner in which these shutters are operated will be nextdescribed.

" Referring to Figs. 14, 15, 26 and 27t he illustrative organization ofchange-throwing mechanism is there well shown. Illustrated more or lessdiagrammatically in Figs. 26 and 27 is the fifty-cent admission key 45and its lever, the fifty-cent admission slide 47 being broken away forsimplification. When the slide 47 is permitted its full upward movementupon due detection of a coin to be admitted, the fifty-cent admissionkey lever 45 strikes" and lifts an overlying arm- 168 of a settingcradle 170 which preliminarily sets the change-throwing mechanismappropriately to the denomination of the admitted coin. The arm 168 ofthe cradle extends over all of the coin-admission key levers for coinsof large enough denomination to require change throwing and may belifted through different distances by the respective levers as presentlyexplained.

' The cradle 170 consists of a frame as shown selective lugs or wards174, 175, 176, 177,-

178, all arranged in the specific mechanism in the same horizontal planeor on the same level, and also a second series of selective lugs orwards 179, 180, 181 and 182, arranged in the same horizontal plane andon a lower level from the other group. Another selective lug or ward 183is arranged at a still lower level. These wards are mounted upon a frame185 which is supported for. endwise sliding movement upon rods 186, 186.The opposite ends of the rods being mounted in slide blocks 188 havingprojections 189 engaging vertical slide ways in' swinging arms 190. Asshown in Fig. 7 the arms 190 are mounted upon a shaft 192 to swingfreely thereon under the control of the change-throwing mechanism.

With the arrangement described, the selector or selector frame 185 ismounted for three different movementsa substantially vertical movement,maybe readily understood by reference to Fig. 18. Each-of thechange-releasing shutters shown in Fig. 13,

of which the dime shutter 194 is shown in Fig.18, has thereon a lug 196,all of the lugs 196 on the several change-releasing shutters being insubstantially the same horizontal plane. The lugs 196 are intended tocotiperate at proper times with the selective wards 174, etc., shown inFig. 7, for instance with the wards 178, 182 and 183 of Fig. 18. Thus ifthe selector 185 be moved a certain distance upwardly from the positionshown in Fig. 18, the top row of wards including the ward 178, willstand opposite the lugs 196; this position being illustrated in Fig. 26.If the selector 185 be elevated V vertically a little farther, thesecond row of wards including the ward 182 of Fig. 18 and the ward 179of Fig. 26, will stand op- .posite the lugs 196; this positionbeingshown in Fig. 27. If the selector 185 be still further elevated, thelowermost single ward 183 will be positioned at the level of 1 missionkey lever 45 is such that the depression of the fifty-cent admission keycan never elevate the selector above the position shown in Fig. 26. Theselector 185 is moved to its intermediate position shown in Fig. 27 bydepressing the twenty-five cent admission key; and is elevatedvertically to its third and uppermost position by depressing the dimeadmission key. Accordingly the selector is initially moved by acoin-admission operation, to a definite'position corresponding to thedenomination of the admitted coin; and to permit the subsequentchange-throwing operation, the selector must .be held in its saidposition by holding the admission key depressed. If the coin admissionkey be released without a changethrowing operation, the selector will beimmediately returned to the inoperative position shown in F ig. 18 bymeans of a spring 198 acting upon the arm 168 of the cradle 170. So longas the coin-admission key corresponding to a coin large enough torequire change, remains depressed, however, at least one of the rows ofselective wards will stand in position to engage one or more of the lugs196 on the change-releasing shutters. Thus, while the selector is heldin elevated position such that some of its selective wards are inposition to strike one or more lugs 196 on the change-throwing shutters,the entire selector is rocked toward the left in Fig. 18 (i. 6. towardthe right in Fig. 26) to the position shown in Fig. 26 whereby atemporary floor 160 positioned under a storage raceway is displaced frombeneath the raceway and is replaced by a slot permitting a coin to dropout of the raceway.

For convenience in description, a cycleof change-throwing operationswill be explained on the 7 initial assumption that a fifty-cent piecehas been deposited in the machine. The fifty-cent piece is admitted tothe machine by depressing the fifty-cent admission key 15 which liftsthe cradle 170 by its arm 168 and thereby lifts the selector 185.

.all to the positions shown in Fig. 26. This places the uppermost row ofselective wards opposite the lugs 196 on the change-releasing shutters,this row of lugs including the wards 174, 175, 176, 177 and 178, shownin Fig. 17. These are shown in plan view in Fig. 19. It is evident thatthe cotiperation between the wards and the several lugs 196 on thecoin-releasing shutters will depend upon' the horizontal position of theselector 185. For instance, in its normal position of rest, the selectorstands as in Fig. 19 being there held yieldingly by a spring 200'shownin Fig. 16. \Vhen thus adjusted the ward 174 stands in position tostrike the lug 196 on the quarter releasing shutter 202; neither the lug175 nor 176 is in position to strike the lug 196 on the nickel releasingshutter 204 which will therefore remain idle. The ward 177 standsopposite the lug 196 of the first dime-releasing shutter 206; and theward 178 stands opposite the lug 196 on the second-dime-releasingshutter 208. If, with these adjustments, the selector 185 be swung onthe shaft 192 toward the left in Fig. 18, i. e. toward the right in Fig.26 or toward the top of the sheet in Fig. 19, the quarter shutter 202and the two dime shutters will be rocked toward the left in Fig. 18 torelease a quarter and two dimes which will drop into thechange-receiving pocket 210 shown in Fig. 7. Thus, with the describedadjustment, an aggregate of forty-five cents in change is thrown.

To cause 'the described movement of the selector on the shaft 192 forthe final step in change-throwing operation, any one of a number ofchange-throwing keys or the like may be employed, as for instance, thekeys bearing the numerals 1 to 10 inclusive shown at the left of Fig.14. The numerals on said keys indicate the number of five cent fares tobe retained in the machine while by depressing any particular lever acertain amount of change is thrown, equaling the difiererice between theretained fares and the amount of an admitted coin, for instance, the onefare' key comprises a lever 212; the two fare key a lever 214; the threefare key a lever 215; the four fare key a lever 216-; the five fare keya lever 217. All of the levers 212 to 217 inclusive may beexactly likethe lever 217 shown in Fig. 26, the same having a change-throwing pusher219 to strike against the rear of the selector 185 to force the sametoward the right in Fig. 26 to the position there shown. In said Fig. 26the lever 217 is shown as-depressed. In Fig. 27 the lever 217 is shownin its normal position of rest in which it is held by a spring 220,similar springs being applied preferably to the pusher arms of all ofthe levers 212 to 217 inclusive.

The six to ten-fare levers inclusive, shown in Fig. 14, will bedisregarded for the present.

Bearing in mind that the pusher arm 219 of the-lever'212 shown-incross-section in Fig. 19 is, in the specific machine, identical inconstruction with the lever 217 and pusher arm 219 of Fig. 26, it willbe remembered that when the one fare key is depressed the lever 212 inFig. 19 will be rocked to the position shown in Fig. 20' by which theselector 185 is pressed forwardly to operate the quarter and two dimeshutters; in other words, with the described adjustment of the selector185 resulting from depression of the fifty-cent admission key thesubsequent depression of the one fare lever which is intended to retaina five cent fare, operates to throw forty-five cents in change. Upondepressing the two fare key lever 214 the latter strikes a cam 230 fixedupon the selector frame 185 as shown in perspective in Fig. 16. It willbe remembered that the selector frame 185 is horizontally slidable onthe rods 186 against the tension of the spring 200; and accordinglywhen'the two-fare .le-

ver 214 is rocked to the position shown in Fig. 21, the selector frame185 with its change-throwing wards will be moved horizontally a certaindistance to the left from the position shown' in Fig. 20, with theresult well shown in Fig. 21, z. e. the ward 174 beingof extensivehorizontal length, is still in position to engage the lug 196 of thequarter shutter 202; the ward 176, is moved to position to cooperatewith the lug 196 of the nickel shutter 204; the ward 177 is moved out ofoperative relation with the lug 196 of the dime shutter 206, and the.ward 178, being of considerable horizontal extent, is still in positionto engage the lug 196 of the dime shutter 208. The described horizontalendwise shifting of the selector 185 is effected by the preliminaryengagement of the cam 230 by the two-fare lever 214; and the finalmovement of the two-fare lever 214 moves the entire selector and itssupporting frame toward the shutter to operate the quarter shutter, thenickel shutter and one of the dime shutters, the second dime shutter 206remaining idle.- In this manner, when depression of the 50 centadmission key has admitted a fifty-cent piece and thereby elevated theselector 185 vertically to the proper level for change-throw ing from afifty-cent piece, subsequent depression of the two-fare lever throws outa quarter, a nickel and a dime aggregating forty cents.

As shown in Fig. 22, operation of the three-fare lever 215 first shiftsthe selector 185 still farther to the left by means of a cam 232 so thatthe ward'174 still engages the lug of the quarter slide 202. The ward176 is moved out of cooperate relation with the lug 196 of the nickelshutter 204 and said lug 196 then stands between the ward 176 and theward 175. The ward 177 remains in inoperative relation to the lug 196 ofthe dime shutter 206; and the ward 178 remains inoperative with the lug196 of the dime shutter 208. Final operation of the three-fare lever215, therefore, throws a quarter and a? dime only, the nickel shutter204 and the second dime shutter 206 remaining idle. Thus, after afifty-cent piece has been admitted by depressing the fiftycent admissionkey, operation of the threefare lever shows an aggregate of thirty-fivecents in change.

As shown in Fig. 23,-operation of the four-fare lever 216 moves theselector 185 still farther to the left by means of a cam 234 with theresult that the ward 174 remains in operative relation to the lug 176 ofthe nickel shutter 202, the Ward 175 enters into operative relation withthe lug 196 of the nickel shutter 204; and both the wards 177 and 178are inoperative in respect to the two dime shutters. Thus, thefifty-cent piece lever having been admitted by depressing thefifty-centadmission key,

. fare lever 217 moves the selector 185 still farther to the left bymeans of a cam 236 with the result that the ward 174 alone continues inoperative relation with the lug 196 of the quarter shutter 202, all oftheother wards being inoperative. Accordingly, afifty-cent piece havingbeen admitted by depression of the fifty cent admission key, subsequentoperation of the five-fare lever 217 throws only a quarter in change.

Whenever a shutter is moved from the idle position of Fig. 18 to thecoin-releasing .position of Figs. 26 or 27, the appropriate coin isreleased, and the next following coin in the storage raceway is helddetained against escape by means of detents 240 shown in Figs. 13, 18,26 and 27. The arrangement of these detents is preferably such that solong as a shutter remains in projected coin-releasing position, anduntil the shutter returns to the idle position of Fig. 18, the detentwill hold the next following coin in the raceway againstv any possibleadvance travel. WVitlrsuch an arrangement the release of one coin mustbe effected completely, and the shutter must be returned thereafter tothe idle position of Fig. 18, be-

fore the next following coin can move into the positions shown in Fig.13 from which positions the same may be released.

It is desired to prevent the possibility'of more than a singlechange-throwing operation for each operation of a coin admission key,thereby precluding the release of more than a single batch of change foreach coin admitted. This may be effected for the purposes of thespecific machine by a locking device well shown in Figs. 15, 18, 26 and27.

Referring particularly to Figs. 15 and 18, the locking device comprisesa preferably heavy leaf spring 242 having its lower end fixed to aconvenient frame piece 243, the tendency of the spring being to rockclockwise in Fig. 18. The spring 242 carriers a block 244 which normallyunderlies the lower end of one of the arms 192 upon which the selector185 swings toward and from the change releasing shutters. The normalrelation of the block 244 and arm 192 are well shown in Figs. 16 and 18,the constant tendency of the spring being to press the block 244upwardly against the bottom of the arm 192. \Vhen, in a change-throwingoperation, the selector 185 and arms 192 are moved toward the left inFig. 18 (as by depressing one of the two-fare levers 212,

etc.,) the lower end of the arm 192 is moved toward the left beyond theblock 244 which is thereupon sprung upwardly by the spring 242 intoposition at the right of the arm 192 to engage the arm 192 and preventthe return'of said arm and the selector 185 to the idle position of Fig.18, until the spring 242 and its block 244 have been deliberatelydepressed to release the arm 192 from the looking effect of. the block244.

Referring now to Fig. l5'a finger 250 fixed upon the setting cradle 170overlies the spring 242, as well shown also in Figs. 16 and 18. When thecradle 170 is locked by depression of a coin admission key, the finger270 is lifted leaving the spring 242 free to move the block244 upwardlyfor the described locking action when the arm 192 is rocked to the leftin Fig. 18 for a changethrowingoperation. So long as the finger 250remains elevated (and it will so remain so long as a coin admission keyremains depressed) the block 244 will continue to lock the arm 192 andselector in coin-releasing position, thereby holding the detents 240 ofFig. 13 in position to prevent any additional coins entering theposition from which they may be released. lVhen, however, a coinadmission key is released, permitting it and the cradle 170 to' berocked clockwise in Figs. 26 and 27 to their positions of rest, thefinger 250 is thereby pressed down against its spring 242 forcing thesame downwardly and removing the block 244 from the rear of the arm 192and permitting the same to return to the position of rest shown in Fig.18.

With the illustrative organization hereinbefore described, nochange-throwing operation is possible except upon depression of theappropriate admission key and continuous retention of the key indepressed position, with the consequent rocking of the cradle 170 in acontra-clockwise direction in Figs. 26 and 27 and the maintenance of thecradle in the position to which it is so rocked. Such movement of thecoin-admission mechanism permits a single change throwing operationafter which the changethrowing mechanism. particularly the selector 185,is locked by the block 244 and spring 242 against a retraction of thechange-throwing operation, until the coin-admission key is releasedcompletely so that a subsequent depression thereof will be prevented byits slide locking lever 50 shown in Fig. 3, except upon the deposit anddue detection of another coin of suitable denomination.

The description will next be directed to change-throwing operations inwhich. afteradmission of a fifty-cent piece, it is desired to retain inthe machine from six to ten fares.

Referring to Fig. 25the one-fare lever 212 is there shown with itspusher 219, and

also a six-fare lever 260 with its pusher 261. The pushers 219 and 261stand preferably in the same vertical plane as shown in Fig. 19. In thesame manner as shown in Fig. 25, the seven-fare lever 262 and its pusher263 are associated with the two-fare lever 214; and the eight-fare lever264 with its pusher 265 are associated with the threefare lever 215; anda nine-fare lever 266 with its pusher 267 is associated with thefour-fare lever 216; and a ten-fare lever 268 with its pusher 269 isassociated with the five-fare lever 217. Obviously, the six to ten-farelevers 260, etc., are intended to be operated for throwing change onlyupon admission of a fifty-cent piece by depressing the fifty-centadmission key. It is evident that, from an admitted fifty-cent piece thesix-fare lever should throw the same amount of change as the one-farelever, minus a quarter; and the seven-fare lever should throw the sameamount of change as the two-fare lever, minus a quarter; and theeight-fare lever should throw' the same amount of change as thethree-fare lever, minus a quarter; and the nine-fare lever should throwthe same amount of change as the four-fare lever, minus a quarter; andthe ten-fare lever should throw the same amount of change as thefive-fare lever,

minus a quarter, that is to say the ten fare lever should throw nochange at all. Obviously, therefore, the six to ten-fare levers 260 and268 may operate in exactly the same manner as the corresponding leversof the one to five-fa re group, omitting only the operation of thequarter shutter which is necessary for the one to five-fare group butmust be excluded for the six to ten-fare group. As already described,depression of the fifty-cent admission key elevates the selector 185 tosuch a point that its upper row of wards 174, 175, 176, 177 and 178 arepositioned on the same level with the lugs 196 on the shutters. If nowthe selector 185 be slightly further elevated, the effect will be tolift the quarter throwing ward 174 above the level of the lug 196 of thequarter shutter 202 so that the latter cannot be operated;

group of fare levers, it is only necessary, in

the specific mechanism, to lift the selector 185 vertically to the nextposition above that to which it is moved by depressing the fifty-centlever. This may be effected in the manner about to be described.

Referring now to Fig. 26-depression of the fifty-cent admission key 45lifts the secontra-clockwise from the position ofF-ig' 26 to theposition of Fig. 27. The-heel 272 is provided with a cam on its lowersurface which strikes a cam lug 274 on the cradle 170 and rocks saidcradle slightly beyond the position to which it was previously rocked bydepression of the fifty-cent admission key and thereby elevates theselector 185 with its wards, to the position shown in Fig. 27 in whichthe intermediate horizontal series of wards is positioned on the samelevel of the lugs 192 of the coin-releasing shutters. In other words,depression of the fifty-cent admission key lifts the selector and itswards to the Fig. 26 position appropriate to coiiperation with the oneto fivefare group of fare keys; and thereupon each of the six toten-fare group of fare keys, is arranged to elevate the selector stillfurther to the Fig. 27 position, the sole effect of such furtherelevation being to eliminate the quarter throwing operation whilemaintaining the dime and nickel throwing connections exactly as they arefor coiiperation with the one to five-fare group of fare levers.

Referring now to Fig. 19-when the parts occupy the position shown inFig. 27, the parts are also as shown in Fig. 19 except that the ward 174is inoperative, being above the level of the lug 196 on thequarter-releasing 202. As shown in Fig. 17, each of the wards 175, 176,177 and 178 are exactly duplicated on the next lower level. Hencedepression of the six-fare lever 260 will operate only the two dimereleasing shuters 208 and 206 to throw an aggregate of twenty cents. Thesix-fare lever 262, seven-fare lever 264, eight-fare lever 2.66 andnine-fare lever 268 operate respectively the cams 230, 232, 234 and 236as already described and Figs. 19 to 24 inclusive represents effects ofdepressing consecutively the six to ten-fare levers,

bearing in mind, of course, that the quarter shutter is not operated inany such cases.

It is desirable to prevent operation of any key of the six to ten-faregroup except when preceded by depression of the fifty-cent admissionkey. This may be effected readily by the illustrative construction shownin Figs. 2, 25,26 and 27.

Referring to Fig. 2a locking bar 280 is pivoted on a frame bracket 281to move in a substantially vertical plane. As shown in Fig. 25 thelocking bar 280, the parts being there in their position of rest, standsadjacent the heels 272 of the levers of the six to ten-fare group. Foreach heel 272 said bar carries a locking tooth 282 adapted to engage alocking seat on the heel 272 to prevent any depression of one of thefare keys, as for instance, the fare key 260 shown in Fig. 25. Revertingto Fig. 2, the right hand end of the locking bar is pivotally connectedto a lug 284 on the fifty-cent admission key 45, the same being shownalso in Figs. 26 and 27. The bar 280 has a jog 286 which permits it topass beneath the quarter admission key 82, the dime admission key 98 andthe nickel admission key 96 without being affected by depression of anykey except the fifty-cent admission key 45 to which the bar 280 isconnected. So

- long as the fifty-cent admission key 45 remains in the position ofrest shown in Figs. 2 and 25, the locking tooth 282 will hold the farekeys of the six to ten-fare group against depression. When, however, thefifty-cent admission key 45 is depressed the locking teeth 282 arewithdraw and the fare keys may be depressed to throw change. Thefifty-cent adinission key may be released while the ten-fare lever 268occupies the. position shown in Fig. 27 and when the fare key 268.;isreleased it will strike the inclined rear face of the tooth 282 andslightly spring the locking rod 280 until the tooth 282 enters its seaton the heel 272 and locks the same.

The position to which the selector 185 is moved by depressing a fare key.268 in Fig.

27 and thereby rocking the cradle 170z'. e. the position in which theintermediate series of wards 179, etc., stand at the same level with thelugs 192, 196, of the change-releasing shutters-is the same position towhich the selector 185 is lifted bv depressing the quarter admissionkey; and the dimensions and throw of the quarter admission key arepredetermined to suit this purpose. As will be understood, depression ofthe quarter admission key lifts all the fare keys of the six to ten faregroup locked by thelocking teeth 282 so that only the one to five-faregroup of fare keys can be depressed following the admission of aquarter. Thus the depression of any key of the one to five-fare groupwill throw the same change combinations illustrated in Figs. 19 to 24inclusive, except that the releasing of a twenty-five cent piece will beomitted in each case.

When a dime admission key is depressed, the selector 185 is lifted tothe uppermost limit of its vertical movement in which the;

single. ward 183 (Fig. 17) is alone on the level of the change-releasingshutter lugs 196. This wardl83 is shown shaded in Fig. 19 with theselector 185 in its normal position of rest as regards its endwisemovement sliding on the rods --186. Thus, by depressing the dimeadmission key the ward 183 in Fig. 19 is lifted to position to cooperatewith the lug 196 of the nickel shutter 204. If, under thesecircumstances, the single fare lever 212 is operated as shown in Fig.20, a nickel alone will be released. If the two-fare lever 214 bedepressed the selector 185 will be shifted to the left by reason of thecam 230 so that the ward 183 will be inoperative in respect to thenickel shutter, all of the other wards being likewise inoperativebecause above the level of the lugs 196 on the several shutters. Thus,upon depression of a dime admission key, there can be but a singlechange-throwing operation consisting in throwing a nickel by depressionof the single fare lever.

It is preferred that every change-throwing operation, or in other wordsevery fare retaining operation, be recorded .or registered, and for thispurpose suitable registers are shown in Figs. 2, 7, and 28 to 31inclusive. Corresponding to each fare lever is a register 290 shown inFig. 28, said register being, if desired, of a well-known Veeder typeand adapted to be operated by a ratchet 292. The register may be arranged upon a shaft 294 conveniently located in the machine and thereoperated by pawls 296 mounted one upon each fare key. Fig. 29 shows apawl on the fare key of the one to five-fare group; and Fig. 25 showscorresponding pawls on fare keys of both groups.

'As shown in Fig. 2v a drawer 300 is provided at the bottom of themachine of which a compartment 302 stands directly beneath thevertically disposed fifty-cent chute 68 to receive the fifty cent piecesfrom said chute. In said drawer there is also a quarter compartment 304,a nickel compartment 306 and a dime compartment 307. Normally, as

already described, there is a supply of quarters, dimes and nickels inthe several storage raceways, where said coins are held to be thrownwhen necessary as change. When it is desired to exhaust the machine, itis preferred to release the coins from all the storage raceways into thedrawer 300. For this purpose the illustrative organization comprisesauxiliary coin-releasing shutter operating mechanism shown in Figs. 27and 32. Mounted under each of the quarter releasing shutter 202, thenickel releasing shutter 204 and the dime releasing shutter 208, is aslide bar. 310. The quarter slide bar 310 has a handle 312 shown inFigs. 7 and 32; the nickel slide bar has a handle 314 and the dime slidebar has a handle 316. Each slide bar (Fig. 7) has a lug 318 in positionto engage a corresponding lug 319 fiked to the appropriatecoin-releasing shutter so that when the slide bar- 310 is pulled to theleft in Fig. 7 by its handle, the lug 318 will strike the lug 319 androck the coinreleasing shutter to coin releasing position. In theordinary change-throwing operation of the machine coin so released wouldbe dropped into the pocket 210; but as shown in Fig. 32, said pocket 210is provided with a false wall 325 adapted to be rocked out from underreleased coins by Operation of the auxiliary coin-releasing slide 310.The falsewa-ll 325 is pivoted on a shaft 326 and an arm 327 of said wall325 is connected by a pin-and-slot connection with the slide rod 310.When the slide rod 310 is moved to the leftin Fig. 32, the false wall325 is rocked to the position shown to permit the released coin 330 todrop down in the rear of the false wall and into the appropriatecompartment in the drawer 300 beneath. As shown in Fig. 7 the exteriorcasing 332 completely incloses the false wall 325 and the lifting ofsaid wall to the Fig. 32'position serves to interpose the wall .betweenreleased coins and the exterior of the pocket-so as to preventextraction of the released coins. When a coin'isinser'ted in the hopper30, for instan'c'ea fifty-cent piece, the fifty-cent admission lever"i's'thereby permitted its full depression to set thechange-throwingme'ch-v anism in operative condition. If, at the sametime, it were possible to operate the coin-discarding mechanismhereinbefore described. and shown in Figs. 3, 4 and 5, it

might be possible to throw a batch of change 7 and at the same timediscard and release the coin with reference to which the change wasthrown. To prevent such fraud upon the machine, it is preferred thatmeans be provided to prevent operation of the discarding mechanismwhenever a coin admission key is depressed to initiate a change-throwingoperation. Means to this end is shown in Fig. 3 comprising a lock 400fixed rigidly upon a shaft 402 suitably'journaled in the machine frameas shown' in Fig. 14. The shaft 402 has fixed thereupon fingers 403, 404and 405 overlying respectively the inner ends of the dime, quarter andfifty-cent admission key levers. The lock 400 is held normally in theposition shown in Fig. 31 by a spring 406 and in such position said lockleaves the coin-rejecting lever 38 free to operate to reject a coin. If,however, one of the coin admission keys is depressed even slightly, itserves to rock one of the fingers 403, 404, 405, together with the shaft402 and lock 400 clockwise in Fig. 3 so as to position the lock 400between the shaft 402 and toe 408 on the coin rejecting lever 38,thereby positively locking the coin-rejecting mechanism againstoperation.

It will be understood that the above described mechanism of the-specificmachine is preferred to be inclosed in a suitable casing such as thatrepresented in Figs. 1, 2, 7

, and 14. The casing may be of any practicable deslgn as will appear tothose skilled in the art.

Referring-to Figs. 1 and 1". It is preferred to employ some means forkeeping continuously closed the slot through which a coin is initiallyintroduced to the machine. For this purpose a hopper 500 may be providedin which the coin is initially deposited, the hopper having therein a.swinging gate 501. The gate 501 preferably is pivoted at 502 to thehopper 500, and has at its upper end. a coin-receiving incline 503 andat its lower edge a second coin-receiving incline 504. The illustrativegate 501 preferably occupies substantially an entire side of the hopper500 and its inclines 503 and 504 extend horizontally clear across thehopper 500 and project into and across the hopper alternately in suchmanner that when one of said inclines is moved so as to open the coinpassage in the hopper the other said incline is therebymoved so as toclose the coin passage in the hopper. For instance, as shown in Fig. 1,a coin may be moved downwardly against the incline 503, thereby rockingthe gate 501 clockwise until the upper edge of the coin has dropped pastthe lower end of the incline 503. Thereupon the coin strikes the incline504 and rocks the gate 501 contraclockwise to permit the coin to passthe latter and enter the coin-receiving hopper 30. Preferably thehopper. 500 and gate 501 are completely inclos'ed within a casing 506,which prevents any tampering with the parts.

It is to be understood that this invention is by no means limited to thespecific organlzation, construction and mode of operation hereinbeforedescribed for purposes of illustration; on the contrary, the inventionmay be. variously embodied as an entirety or as to its separatefeatures, and may be var ously practised within the scope of thesub]oined claims.
